G50 series

INNOVATIVE ADDITION TO GLOBAL SERIES!

■ Key Features
INTERCHANGEABLE
Looking for longer life from your diaphragm pumps? The G50 is a direct drop-in replacement to existing brands, making a pump change out easy without a need to reconfigure piping.

LIGHTWEIGHT
The G50 is the lightest 2" aluminum pump among competitive brands, making it perfect for portability and placing in those hard to get areas.

EASE OF MAINTENANCE
The G50 features the fewest total parts, but also the least number of wearing parts, making it ideal for quick and inexpensive rebuilds.

LUBE FREE, NON-STALL AIR VALVE TECHNOLOGY
The G50 uses the field proven C Spool technology borrowed from the NDP series. It never requires lubrication and is component replaceable, so no need to replace worn parts with expensive assemblies.

■ Main Applications
Pumping Out Sprays, Factory Wastewater, and Waste Oil/Supplying Oil, Coolant Fluid, Paint, Etc./Alcohol/Transfer of Ethanol/Pumping Out Sprays, Factory Wastewater, and Waste Oil/Transfer of Flammable Liquids in Explosion-proof Areas/Transfer of Inks and Pigments/Mounting on Equipment/Transfer of Lubricant and Hydraulic Oil/

Features

■ Independent Left and Right Pilot Valves
These activate the air switch valve at the stroke limit, and are also completely oil-free. Dynamic seals are eliminated as independent left and right types.
It is resistant to abrasion and ensures stable pump operation over a long period of time.

■ Yamada’s Proprietary Design Air Switch Valve “C-Spool”

The air switch valve in the center section of the diaphragm pump is completely oil-free, so it does not require regular lubrication.
The operation assist using a C-spring suppresses stoppages during operation, and achieves stable operation.

◆ Air Switch Valve “C-Spool”

The C-spring Prevents Stoppages during Operation
Achieves stable operation.
Equipped with a Reset Button
Downtime due to pump stoppages in the case of wear of the air switch valve is kept to a minimum.

Completely Oil-free
Both the air switch valve and the pilot valve that activates the air switch valve at the stroke limit are designed to be oil-free. Does not require regular lubrication.
Simple Replacement
No need to disassemble the pump when replacing it.
